Sense Sonnet - Steamer

Fast Learner

I got a call to my son's school.
So I showed up, expecting that
My son had broken some small rule,
And this was just a friendly chat.
The principal was quite upset,
Saying my son started a club,
That focused on the alphabet.
Sounded okay - but then the rub.
Each letter stood for a sex act,
That the kids would then demonstrate
With each other in close contact.
The beans were spilled by a classmate.

I can't believe what I was told.
My son is only 6 years old!
